Surrounded by countries under the bloody siege of jihad, this is not surprising. Angola is taking steps at self-preservation on a continent where countries are getting swallowed whole by jihadists enforcing the sharia. It's a defensive move.
Angola 'Bans Islam', Dismantles Mosques, According To News Reports By IBTimes (thanks to Narain)November 24 2013,
A number of news outlets have reported that the Southwest African nation of Angola has "banned" Islam and started to dismantle mosques in a bold effort to stem the spread of Muslim extremism.
Weekly French-language Moroccan newspaper La Nouvelle Tribune published an article on Friday sourcing "several" Angolan officials, including the country's Minister of Culture, Rosa Cruz, who reportedly offered the following remarks, which have been translated from French:
"The process of legalization of Islam has not been approved by the Ministry of Justice and Human Rights, their mosques would be closed until further notice." The media reports did not describe why exactly Islam apparently faces a need to be legalized despite having had a presence in the country for many years.
OnIslam.net reports that the African economic news agency Agence Ecofin wrote that Cruz made the statement at an appearance last week before the 6th Commission of the National Assembly. The website goes on to report that, "According to several Angolan newspapers, Angola has become the first country in the world to ban Islam and Muslims, taking first measures by destroying mosques in the country."
UPDATE: "Angola Denies It Banned Islam, Destroyed Mosques" International Business Times
I suspect Islamic sites advanced this story to incite jihad and violence against Angola.
Robert Spencer comments: "I doubted the accuracy of this report from the beginning, and sure enough, it turns out to be false. That is all to the good -- banning an entire belief system would just embroil Angola in an ongoing resistance and would become a serious human rights issue. Banning Islam in particular would engulf it in a more energetic jihad than is being waged against it now."
